They were around a very long time but I was never into their tear jerkers. That 25 6 to 4 song was a good one, one of their earliest songs..
I dunno it's cause I grew up there, but I always liked Chicago. They were around for a long time and Chicago 19 was released in '88. That was their last good album. We had the CD and listened to it a lot cleaning the house on the weekends. It was all fun Saturday morning cartoons (that's not even a thing anymore), until my dad woke up and came down stairs ... then it was scrubbing and cleaning and dusting and vacuuming and mopping all day.
